Filter.



NITED Sn'rns CHARLES EDOUARD CIIAMBERLAND, OF PARIS, FRANCE.

FILTER.

SEEGIFICATION forming part of Letters Patent No. 695,375, dated March 11, 1902.

Application filed August 19, 1901. Serial No. 72,561. (lilo model.)

To @ZZ whom it may 'concer-72,.-

Be it known that I, CHARLES EDOUARD CHAMBERLAND, a citizen'of the Republic of France,residing at Paris, France, have invented a certainnew and useful Improvement in Filters, (for which I have secured Letters Patent in France under date of February 1, 1901, No. 307,7235) and I do hereby declare that the following is a full, clear, and exact specification of the same.

The object I have in view is to provide a filter whichshall be cheap to manufacture and which shall besides be capable of being readily taken apart and put together again.

The herein-described filter is more particularly designed for water; but it can be utilized with equal advantages for filtering wine and other beverages and all liquids generally.

The ltering medium used in the filter to be herein described may be composed of any approved substance or substances. I prefer, however, to produce it 'from the substances and in the manner set forth in my prior patents ot the United States, numbered 336,385 and 330,386 and dated February 16, 1886. The filtering medium may be cylindrical or of any other approved shape, a number of the filtering-bodies being preferably groupedtogether, so as to embrace a multiple of filtering elements in one single filtering apparatus.

An approved form of filtering-body may resemble the body set forth and illustrated in my prior patent of the United States, numbered 336,089 and dated February 16, 1886, the body filtering either from the outside to the inside, or Vice versa.

In the filter herein described the filtering operation takes place from the outside to the inside of the hollow body.

In the accompanying drawings, Figure 1 is- Referring to Figs. 1 and 2, ct a a are cylinders each intended to contain a filtering-body Z2 of any approved form. Preference should, however, be given to the well-known Cham'- berland-Pasteur filtering-body, formed with a collar or flange c, unprovided with a nipple, as devised by me andpatented in France under date of March 17, 1900, No. 298,311.' All the cylinders a are cast in one single piece (cast-iron, copper, or other suitable metal or material) with a pipe d, by which the water to be liltered is supplied. The filtering-bodies l) are placed in the cylinders ct with their iiange c bearing upon the top of the same, a proper joint being obtained, as usual, by a suitable packing. The bodies b all connect with a pipe f, wherein is gathered the filtered water and whereby the lat-ter is supplied to consumption. The pipe f has as many covers and joints as there are bodies b, the joints between the flanges c of the said bodies and the covers being likewise obtained by a suitable packing. An opening g, formed opposite each body b, connects the inside of the latter with the inside of the collecting-pipe f. The collecting-pipe fris fastened to 4thecylinders a, while at the same time producing a Water-tight joint by "means of a number of screW-stirrups h or their mechanical equivalent, such as a clamping device with a bayonet-joint or the like.

Taken as a whole, the herein-described apparatus may constitute a unit, of which a num-V ber may be grouped to form a battery of great capacity, for which 'purpose the inlet-pipe d, which supplies the water'to be filtered, is provided at each end with iianges 7o for connecting the units together. Lugst't' may be formed on each unit for fastening the same to a wall or other support.

Referring to Fig. 3, l have shown an arrangement which is similar to the arrangement shown in Figs. 1 and 2, with this difference, that instead of having a number of Vfiltering bodies the apparatus only contains one. Excepting this difference the arrangement remains the same, thesame letters of reference designating the same parts.

Referring to Figs. 4 and 5, I have shown how all the filtering-bodies may be grouped, not singly in a series of cylinders, as shown in Fig. 1, but collectively in a common vessel a',

IOO

the upper opening ff of which is closed by a perforated plate Z, through the perforations of which are passed the bodies b, so as to bear with their Iianges c upon the said plate. Over 5 the said plate Z is placed the headf', which connects with the Harige c of each body and forms therewith a water-tight joint by means of a suitable packing, as in the case of Figs. l and 2. Between the perforated plate Z and Io the vessel o: is also interposed a suitable packing m,wherebyawatertight joint is obtained. The Whole is clamped together by means of bolts, stirrups, or equivalent devices 71,. water to be filtered enters at Cl, and the filtered The I portion of the apparatus, which is cast n one piece with the Water-inlet pipe CZ, Fig. 1.

I claim- Y Aiilter comprising a plurality of cylinders for containing eacha ltering-body, formed in one piece with the inlet-pipe for the liquid to be filtered, combined with a cover formed in one piece with the outlet-pipe for the ltered liquid, means for securing liquid-tight joints between the filtering-bodies. and the said cylinders on the one hand and the said cover on the other, and means for clamping the said cover, substantially as herein described and shown.

In Witness whereof I have hereunto set my hand, this 6th day of August, 1901, in the pres;

ence of two subscribing witnesses.
